SELF-CLOSING FAUCET.

.SIPEGIFIGATION forming part of Letters Patent No. 249,579, datedNovember 15, 1881.

Application filed May 25, 1881. (No model.)

To all whom it may concern Be it known thatwe, JAMES E. BOYLE and HENRY,HUTBER, both citizens of the United States, residing, respectively, inBrooklyn, Kings county, New York, and in New York city, New York, haveinvented certain Imon its seat normally by a spring, and is liftedprovements in Self-Closing (looks or Faucets,

of which the following is a specification.

This invention relates to that class of cocks orfaucets in which thevalve is held down upfrom its seat by means of a lever connected withthestem of the valve.

The purpose of our invention is not to effect any change in theoperation of the cock, but in its construction, whereby its parts may beput together and taken apart with greater l'acility.

In the ordinary construction of these cooks the cheeks of theoperating-lever embrace the projecting end of the valve-stein, and areconnected with the stern by means of a pin which passes through all andscrews into one of the checks of thelever. To cause the spring aroundthe valve-stem todraw the checks of the operating-lever down snugly andelastically upon the cap of the valve-chamber, (whereby looseness andrattling is prevented,) and at the same time permit the spring to seatthe valve properly, it is necessary that the aperture in the stemthrough which the pin passes shall be drilled with absolute accuracy. Tothis end the valve is seated, and the cap through which the stem passesis screwed down firmly to its seat. 'The cheeks of the operating-lever,al-

ready drilled to receive the pin, are now set to ofinsuringthefirmsettingofthelever on the cap of the cock. If the drilling of the stem benot accurately done, either the valve will be lifted fromits seat byforcing in the pin, or the checks of the lever will not rest firmly uponthe cap.

. Moreover, if the holes in the checks of the lever do not coincide withthat in'the stem, it is accuracy is required, is necessarily excessive.

To obviate the abovenamed diflficulties and render the parts of the cocknot only easyto put together, but interchangeable, is the object of ourpresent invention, which we will now describe with reference to theaccompanying drawings, in which- Figure l is a vertical midsectiouthrough the operative parts of a cock constructed accordingto ourinvention. Fig. 2 is a crosssection of the. same, taken in the plane ofthe line 2 2 in Fig. 1. Fig. 3 is afragmentary section taken in theplane of the line 3 3 in Fig. 2. Fig. 4 comprises views of differentforms ofthe cross-pin removed. all

Let A represent the ordinary valvechamber, B the valve, (3 thevalve-stem, I) thespring, and E the cap, of an ordinary self-closingcock. These are all constructed and arranged in the usual way.

To lift the valve from its seat against the elastic resistance of thespring, a lever, F, is employed, the cheeks a a of which rest on the capE, which serves as a fulcrum, thelever being connected with the stem bymeans of a pin, b, which passes through the checks at a and thevalve-stem. The arrangement and operation of these several parts are,broadly speaking, old but the construction which we will now describe isnew, so far as we are aware.

The aperture cin the stem (3, through which the pin b passes, iselongated in the nature of a slot, and anaxial screw, d,is provided,which screws down into said slot through the end of the valve-stem. Thepin 1) is, by preference, slightly reduced in diameter where the saidscrew impinges upon it, so that it cannot play longitudinally. It may beturned to a smaller tened on one or both sides, as shown in Fig. 4. Thehandle 6 of the lever F isdetachable, and screws into the bridge or tief, which con meets the cheeks a a.

In putting the parts of the co'cktogether the valve and spring areproperly placed and the cap E screwed firmly down to its seat-tdiameterat its middle, or it may there be fiat- The cheeks of the leverF are now caused to embrace the protruding end of the valve-stem and thepin 1) passed through. This is rendered easy by the elongation of theaperture 0. The handle '6 is now unscrewed, and the screw d inserted andrun down upon the pin by inserting a screw-driver at the hole in thetief, from which the handle has been removed. The screw is run down onlyfar enough to seat the cheeks a a firmly on the cap E, and not farenough to lift the valve from its seat; and after this adjustment isproperly effected the handle 6 is screwed firmly in, and the cock isready for use. The parts made in this manner are interchangeable, andmay be put together and adjusted with ease, accuracy, and rapidity andwith very little expenditure of skill orjudgment.

We have shown our invention as applied to a cock having avertically-arranged operatinglever; but it may as well be employed incocks having horizontally-arranged levers.

Having thus described our invention, we claim- I. Aself-closing cook orfaucet in which the pin connecting the operating-lever with thevalve-stem passes through a longitudinallyelongated aperturein thestem,.and a screw is arranged axially in the stem and adapted to bearupon the said connecting-pin, whereby the proper adjustment and seati-ngof the operating-lever is effected, substantially as set forth.

2. A self-closing cock or faucet comprising a valve-chamber and cap, avalve and its stem, and a spring to hold the valve down to its seat,

all arranged in the usual way, an operatinglever with two cheeks toembrace the valvestem, a pin to pass through the two checks of thelever, andan elongated aperture in the stem, and anaxial screw in theend of the stem, arranged to enter the aperture in the stem and bearupon the connecting-pin, substantially as and for the purposes setforth.

3. The combination, with thevalve-chamber, its cap, the valve, and thespring, of the valvestem with an elongated aperture to receive theconnecting-pin, and an axial screw to enter said aperture and bear uponsaid pin, the said connecting-pin and the operating-lever provided witha removable handle, whereby the axial screwin the valve-stem may bereached, substantially as set forth.

4. The combination, with the valve-chamber, the valve, its spring, andthe valve-stem provided near its upper end with an elongated slot, andhaving a screw entering said slot from its upper end, the rocker-lever,and a pin adapted to pass through the cheeks of said lever and the saidelongated slot, and reduced in diameter opposite the end of the saidscrew, whereby the end of the screw enters between two shouldersthereon, and the longitudinal displacement of the pin is prevented,substantially as set forth.

In witness whereof we have hereunto signed our names in the presence oftwo subscribing witnesses.
